Description

Round corner trimming knife for wooden door

Technical Field

The utility model relates to a fretwork milling cutter, more specifically say, it relates to a fillet deburring sword for timber.

Background

A fillet trimming knife comprises an L-shaped blade, wherein an arc-shaped knife edge for trimming a wooden door is arranged on the L-shaped blade, the design of a common trimming knife is unreasonable, and when wood is machined, generated sawdust is easy to accumulate beside the blade to influence the machining of the wood by the trimming knife.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a saw-dust that produces during the cutting is difficult for influencing the fillet deburring sword that is used for the timber to the processing of plank.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the utility model provides a fillet deburring sword for timber, including tool bit and cutter arbor, the tool bit is the form of falling T, the tool bit comprises first cutter body and the second cutter body of a body coupling, first cutter body and second cutter body all are the triangular prism form, first cutter body and second cutter body all are L form and first cutter body and second cutter body are about the axis central symmetry of cutter arbor, first cutter body and second cutter body form two blowtanks, all open a location breach on the top of first cutter body and second cutter body, two location breaches communicate each other and two location breaches communicate with two blowtanks respectively, all be fixed with a blade in every blowtank, the location breach all stretches out on the top of blade, two blades are crisscross to be arranged and are parallel, the top of blade is parallel with the top parallel and level of first cutter body, the blowtank extends out to the bottom of blade, the bottom of blade forms the breach of unloading with the bottom surface of tool bit.

Further, the first knife body comprises a first side face and a second side face, the first side face is arc-shaped, a first cut face, a second cut face and a third cut face which are sequentially arranged are formed on the second side face, an arc-shaped cut face corresponding to the knife blade is formed on the top of the second side face, the second cut face and the third cut face are connected with the arc-shaped cut face, an included angle of 170 degrees is formed between the second cut face and the arc-shaped cut face, an obtuse included angle is formed between the third cut face and the arc-shaped cut face, the included angle between the third cut face and the arc-shaped cut face is gradually reduced in the direction from the first cut face to the third cut face, the arc-shaped cut face, the first cut face and the second cut face are connected with the first side face, 90 degrees are formed between the arc-shaped cut face, the first cut face and the second cut face, and the third.

By adopting the technical scheme, the beneficial effects of the utility model are that: the cutter head is more reasonable in design, the blade is stressed more uniformly when in use, and the blade is not easy to damage; when the cutter head cuts wood, the generated sawdust is buffered through the discharge chute, so that the wood is not easy to accumulate at the blade, and further the wood processing is not easy to influence.

Detailed Description

Embodiments of the present invention are further described with reference to fig. 1 to 3.

A round corner trimming knife for a wooden door, which is not easy to influence the processing of a wooden plate by sawdust generated in cutting.

The utility model discloses a concrete implementation scheme: the cutter comprises a cutter head 1 and a cutter bar 2, wherein the cutter head 1 is in an inverted T shape, the cutter head 1 is composed of a first cutter body 3 and a second cutter body 4 which are integrally connected, the first cutter body 3 and the second cutter body 4 are both in a triangular prism shape, the first cutter body 3 and the second cutter body 4 are both in an L shape, the first cutter body 3 and the second cutter body 4 are symmetrical about the axis center of the cutter bar 2, the first cutter body 3 and the second cutter body 4 form two discharge chutes 5, the tops of the first cutter body 3 and the second cutter body 4 are both provided with a positioning notch 6, the two positioning notches 6 are mutually communicated, the two positioning notches 6 are respectively communicated with the two discharge chutes 5, a blade 7 is fixed in each discharge chute 5, the top ends of the blades 7 extend out of the positioning notches 6, the two blades 7 are arranged in a staggered mode and are parallel, the top ends of the blades 7 are parallel to the top end of the first cutter body 3, the bottom ends of the blades 7 extend out of the discharge chutes 5, and the bottom.

The working principle is as follows: when the trimming knife is used, the trimming knife rotates, the two L-shaped blades 7 rotate and trim the wood board, and the generated wood chips enter the two discharging grooves 5 and are driven to enter the two discharging grooves, so that the wood chips are buffered and discharged along with the rotation of the blades 7, and are not easy to accumulate at the blades 7 and the wood board to be processed, and further the processing of the wood is not easy to influence; the blade 7 is matched with the discharge chute 5, so that sawdust generated during processing is buffered more effectively; when blade 7 cuts the plank, the saw-dust can be followed the breach 8 discharge of unloading to make the saw-dust be difficult for piling up in blade 7 department and treat the plank department of processing, and then difficult influence is to ligneous processing.

The first cutter body 3 comprises a first side surface 9 and a second side surface 10, the first side surface 9 is arc-shaped, the second side surface 10 is provided with a first tangent plane 11, a second tangent plane 12 and a third tangent plane 13 which are sequentially arranged, the top of the second side surface 10 is provided with an arc-shaped tangent plane 14 corresponding to the blade 7, the second tangent plane 12 and the third tangent plane 13 are both connected with the arc-shaped tangent plane 14, the second tangent plane 12 and the arc-shaped tangent plane 14 form an included angle of 170 degrees, the third tangent plane 13 and the arc-shaped tangent plane 14 form an obtuse included angle, the included angle is gradually reduced in the direction from the first tangent plane 11 to the third tangent plane 13, the arc-shaped tangent plane 14, the first tangent plane 11 and the second tangent plane 12 are all connected, the arc-shaped section 14, the first section 11 and the second section 12 form an included angle of 90 degrees with the first side surface 9, the first section 11 forms an included angle of 150 degrees with the second section 12, and the second section 12 forms an included angle of 170 degrees with the third section 13.

The crookedness of first side 9 cooperates the crooked edge of a knife of blade 7 to when making the plank deburring, the saw-dust that blade 7 will produce evenly brings into the blowpit 5, along with tool bit 1 rotates, the saw-dust is discharged in by the blowpit 5, and first tangent plane 11, second tangent plane 12 and third tangent plane 13 that connect gradually are more level and smooth, make the saw-dust when discharging under the effect of centrifugal force, the second side 10 is difficult for causing the discharge path of blockking to the saw-dust, thereby make the more smooth and easy discharge of saw-dust, the saw-dust is difficult for piling up the deburring that influences tool bit 1 to the plank.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
